Dry and Warm Weather Lingers Over the Mid-Atlantic Before Late-Week Cool Down

MOUNT HOLLY, NJ — Issued by the National Weather Service at 3:38 AM EDT on October 20, 2024.

Temperatures Rise Into the 70s and 80s Across New Jersey and Delaware

High pressure will keep New Jersey, Delaware, and the Mid-Atlantic warm and dry for the next few days. Highs today will reach the mid-70s, with abundant sunshine clearing out any early morning ground fog across coastal areas like southern New Jersey and Delmarva. Overnight lows will dip into the upper 30s and low 40s, creating crisp mornings throughout the region​

On Tuesday, temperatures will surge even higher, with near-record warmth expected. Forecasted highs in parts of the region, including Philadelphia, could approach the low 80s. This unusually warm stretch will continue until a cold front arrives later in the week.

Cold Front to Bring Limited Rain, but Temperatures Fall by Thursday

The first chance for rain arrives Wednesday night as a cold front moves through, though precipitation is expected to be minimal. The best chances for light rain showers are along and north of the Interstate 78 corridor, but most areas will likely remain dry.

Behind the front, cooler temperatures will return on Thursday, with highs falling back into the 60s. Gusty northwest winds could reach up to 25 mph Thursday afternoon before tapering off by evening.
